Initial velocity of an object
1. The problem statement, all variables and given/known data
What was the initial velocity of an object that moved 120m in 5.60s, reaching a final velocity of 15.0m/s in that time? 2. Relevant equations v=d/t a=v2-v1/t2-t1 3. The attempt at a solution I was wondering is there an acceleration that i'm missing here? or am i just off? I've been using this eq. v1=v2-a(changeintime) Someone help :( |
